Answer:
Explanation:
From the information given:
no of moles of 
= 0.01 L × 0.0010 mol/L
no of moles of = 
no of moles of 
= 0.01 L × 0.00010 mol/L
no of moles of = 
Total volume = 0.02 L
![[Ca^{2+}}] = \dfrac{1\times10^{-5} \ mol}{0.02 \ L} \\ \\ \\ \[[Ca^{2+}}] = 0.0005 \ mol/L](https://tex.z-dn.net/?f=%5BCa%5E%7B2%2B%7D%7D%5D%20%3D%20%5Cdfrac%7B1%5Ctimes10%5E%7B-5%7D%20%5C%20mol%7D%7B0.02%20%5C%20L%7D%20%5C%5C%20%5C%5C%20%20%5C%5C%20%20%5C%5B%5BCa%5E%7B2%2B%7D%7D%5D%20%3D%200.0005%20%5C%20mol%2FL)

![[F^{-}] = 5 \times 10^{-5} \ mol/L](https://tex.z-dn.net/?f=%5BF%5E%7B-%7D%5D%20%3D%205%20%5Ctimes%2010%5E%7B-5%7D%20%20%5C%20mol%2FL)
![Q = [Ca^{2+}][F^-]^2 \\ \\ Q = 0.0005 \times (5\times 10^{-5})^2 \\ \\ Q = 1.25 \times 10^{-12}](https://tex.z-dn.net/?f=Q%20%3D%20%5BCa%5E%7B2%2B%7D%5D%5BF%5E-%5D%5E2%20%5C%5C%20%5C%5C%20Q%20%3D%200.0005%20%5Ctimes%20%285%5Ctimes%2010%5E%7B-5%7D%29%5E2%20%5C%5C%20%5C%5C%20Q%20%3D%201.25%20%5Ctimes%2010%5E%7B-12%7D)
Since Q<ksp, then there will no be any precipitation of CaF2
Answer:
Pressure is inversely proportional to the volume of gas.
Explanation:
According to Boyle's law,
The volume of given amount of gas is inversely proportional to the pressure applied on gas at constant volume and number of moles of gas.
Mathematical expression:
P ∝ 1/ V
P = K/V
PV = K
when volume is changed from V1 to V2 and pressure from P1 to P2 then expression will be.
P1V1 = K P2V2 = K
P1V1 = P2V2
Explanation:
Speed and velocity are both used to describe the motion of a body. But there are differences between the two terms.
- Velocity is the rate of change of displacement with time. It is mathematically expressed below:
Velocity = 
The unit of velocity is m/s or km/hr.
Velocity is a vector quantity that shows magnitude and direction.
- Speed is the rate of change of distance with time. It is concerned with the total length of path a body moves.
Speed = 
It has the same unit as velocity
It is a scalar quantity that has only magnitude.
